THOMAS MUIR, OF MARGARETVILLE, NE\V YORK.

BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 447,157, dated February24, 1891.

' Application filed September 3, 1890. Serial No. 368,824. (No model.)

To all whom it may concern: 7

Be it known that I, THOMAS MUIR, of Margaretville, in the county ofDelaware and State of New York, have invented a new and ImprovedButter-Worker, of which the following is a full, clear, and exactdescription.

The invention relates to butter-workers such as shown and described inthe United States Patent No. 206,036, granted to me July 16, 1878.

The object of the present invention is to provide a new and improvedbutter-worker which is simple and durable in construction and not liableto get out of order by warping, leakage, or other causes. I V

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter, and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement on the line 11 of Fig. 4. Fig. 2 is a transverse section of the same on the line 2 2of Fig. 3. view of part of the improvement on the line 3 3 of Fig. 2.Fig. 4: is a plan view of the improvement, with parts removed, on theline 4 4: of Fig. 1. Fig. 5 is a sectional side elevation of a bearingon the line 5 5 of Fig. 6, and Fig. 6 is an end view of the same.

The improved butter-worker is provided with the stationary table A, madein ring form and supported at its under side on a cross B, resting onlegs 0, and being fastened thereto by lag-screws D, as is plainly shownin Figs. 1, 2, and 4. By removing the lag-screws the legs can be readilydetached from the cross B for conveniently packing the same in shippingthe apparatus.

On top of the table A is formed an annular groove E, leading to a pipeF, for carrying off the milk and water pressed out of the butter. On theinside and on top of the table A is formed an annular track G, on whichare fitted to travel segmental lugs H, secured to the under side of therevolving table I, made in disk shape, and of a number. of boards fittedtogether by tongues and grooves, as is plainly indicated in section inFig. 1. In the Fig. 3 is an inverted plan conjunction with the lugs H,prevents itswarping. The outer ends of the transverse bar J are engagedat their sides by undercut blocks J secured to the under side of thetable I, asis plainly shown in Fig. 3. The segmental lugs H and theblocks J as well as the ends of the bar J, are adapted to travel on theannular track G of the fixed table A, so that the revoluble table I isequally supported on the fixed table A. At. the same time the frictionalcontact of track and table is reduced to a minimum and the table isprevented from warping. Furthermore, the table I, when wet, is free toexpand in line with the transverse bar J, as the latter does not hindersuch movement, but, on the contrary, guides the lateral expansion andcontraction without permitting the table to warp. The undercut blocks Jexpand and shrink with the table, but always remain straight and trueand hold the outer ends of the bar in firm contact with the under sideof the table to prevent the latters warping. In the middle of the bar Jis formed an opening J, engaged by a pin K, supported in the middle ofthe cross B and forming the pivot for the table I. The latter isprovided on the under side, near its outer edge, with an annulargrooveL, which prevents the milk and water, flowing down to the edge of thetable I, from passing to the pivot or to the track G.

Across the top of the table I extends the working lever N, preferably ofdiamond shape in cross-section, as is plainly shown in Fig. 2, andprovided at its outer end with a handle N and formed at its inner endwith a pin N fitting into an arm 0, pivoted in the forked bearing Q,provided in its bottom with;

a pivot -pin Q, engaging a corresponding aperture formed in an extensionB, being part of one of the arms of the cross B. A bolt It passesthrough the pivot Q and the extension B, and is provided on its lowerend with a nut S, screwing against a washer T, held on the under side ofthe extension B.

By this arrangement the working lever N can be turned in the pivoted arm0, and at the same time it'can be moved sidewise by turnin gthe bearingQ in the extension 13, and can be moved up and down by the arm 0,swinging on its pivot P in the said bearing 0.

A butter-workerconstructed in the manner set forth prevents therevolving table I from warping, and at the same time the table can beeasily revolved on the stationary table G, as only the segmental lugs IIand the ends of the bar J travel on the said track.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a butter-worker of the class described,a revoluble table made of a series of boards fitted together withtongues and grooves, segmental lugs secured on the under side of thetable across the said board and near the outer edges of the latter, abar extending in the middle of the said table across the said boards,and undercut blocks secured to the said table and engaging the outerends of the said bar, substantially as shown and described.

2. In abntter-Worker,the combination, with a stationary table made inring shape and provided on top with an annular groove and a circulartrack, of a cross engaging the under side of the said table, legssupporting the said cross and fastened thereto by lag-screws, apivot-pin heldin the center of the said cross, and a revoluble tablemounted to turn on the said pin and provided 011 its under side withsegmental lugs traveling on the said track, substantially as shown anddescribed.

3. In abutter-worker, the combinatiomwith a stationary table made inring shape and provided on top with an annular groove and a circulartrack, of a cross engaging the under side of the said table, legssupporting the said cross and fastened thereto by lag-screws, apivot-pin held in the centerof the said cross, a revoluble table mountedto turn on the said pin and provided on its under side with segmentallugs traveling on the said track, and a transverse bar secured centrallyon the under side .of the said table and-provided with an openingengaged by the said pivot-pin, substantially as shown and described.

a. In abutter-Worker, the combination, with a stationary table made inring shape and provided on top with an annular groove and a circulartrack, of a cross engaging the under side of the said table, legssupporting the said cross and fastened thereto by lag-screws, apivot-pin held in the center of the said cross, a revoluble tablemounted to turn on the said pin and provided on its under side withsegmental lugs traveling on the said track, a transverse bar securedcentrally on the under side of the said table and provided with anopening engaged by the said pivot-pin, and undercut blocks secured onthe under side of the said table and engaging the outer ends of the saidtransverse bar, substantially as shown and described.
